NAME
posix_openpt() - open a pseudo-terminal master device SYNOPSIS
Parameters oflag indicates the file status flags and file access modes of the open file description. Values for oflag are constructed by a bit- wise-inclusive OR of flags from the following list, defined in Open for reading and writing. If set will not cause the terminal device to become the controlling terminal for the process. DESCRIPTION
The function establishes a connection between a master device for a pseudo-terminal and a file descriptor. This file descriptor can be used to refer that device. The file status flags and file access modes of the opened file descriptor will be set according to the value of oflag. RETURN VALUE
Upon successful completion opens a master pseudo-terminal device and returns a non-negative integer representing the lowest numbered unused file descriptor. Otherwise, returns -1 and is set to indicate the error. ERRORS
On failure sets one of the following values for OPEN_MAX file descriptors are currently open in the calling process. The maximum allowable number of files are currently open on the system. The value of oflag is not valid. Out of pseudo-terminal resources. Out of STREAMS resources. AUTHOR
